How we help

Improve communication between visitors and residents with an intercom suited to your building. We plan the entry panel, door release and tenant setup as one system.

Who it's for

  • Landlords and managing agents of walk-ups and elevator buildings
  • Co-op and condo boards replacing a failing buzzer system
  • Owners renovating a lobby or entrance

Suitable properties

Prewar walk-up (3-20 units)
Usually a wired audio or two-wire video system on the existing riser, or a cloud panel if the riser is unusable.
Elevator building (20-100+ units)
Video or cloud panel at the lobby, often integrated with fob access control on the same door.
Condo / co-op lobby
Often a hybrid: cloud panel with phone answering plus optional handsets, approved by the board with written subscription terms.

Main options

Wired audio intercom
New entry panel and in-unit handsets on the existing riser. No monthly fee and works without internet.
Wired video intercom
Two-wire video systems such as Aiphone GT or Comelit carry audio, video and power over existing pairs, with in-unit monitors.
Cloud video intercom
One entry panel at the lobby; residents answer on their phones or by a regular phone call. Little in-unit wiring, but a recurring subscription.
Hybrid
A cloud panel at the street door with optional in-unit handsets for residents who prefer one.

Survey, installation and support

  1. 01A site survey tests the existing riser, door release, power and network at the lobby.
  2. 02The system is designed around the building's wiring and budget: wired handsets, cloud video or a hybrid.
  3. 03You receive a written, itemized proposal listing hardware, labor, any subscription and what the board or owner must approve.
  4. 04The entry panel, door release and in-unit stations or app accounts are installed, usually staged so the door is never left unsecured overnight.
  5. 05Handover covers programming and a walk-through with the super or managing agent, plus a short tenant guide.
  6. 06Ongoing support covers panel faults, door release failures and directory updates.

Typical timeline: 2-5 working days on site for most 6-40 unit buildings, after a survey

Compatibility and limits

  • A corroded or heavily spliced riser may not carry a two-wire video signal; this is only known after testing pair by pair.
  • Cloud panels depend on the building's internet connection unless a cellular backup is added.
  • A new intercom will not fix a worn electric strike, closer or misaligned door; those are separate repairs.

Wired intercom or cloud intercom: which is better for a co-op or condo?

Read the answer

A wired system has no monthly fee, keeps working if the internet goes down and is familiar to older residents. Its weaknesses are cost per apartment and limited remote features: if nobody is home, nobody can let the delivery in.

A cloud system adds remote answering, virtual keys for guests and cleaners, delivery logs and directory changes made from a browser instead of a service call. In return it depends on the building's internet connection and on a vendor subscription. A cellular backup or a dedicated internet line for the panel is a sensible addition on any cloud install.

Many co-op boards choose a hybrid: a cloud panel at the street door with phone answering, and an option to keep a basic in-unit handset for residents who want one. Whatever you choose, the board should get the subscription terms in writing before approving it.
